Description
Technical field
The present invention relates to a kind of surgical operation assistive device, particularly a kind of knee surgery regulates fixedly dilator.
Background technology
Knee joint is one of joint of the most easily damaging of human body.During knee joint activity, between femur, tibia and patella, produce contact and extruding, trauma infection contamination, strain, deformity or degenerative change etc. all easily cause pathologic changes of knee joint, common as subluxation outside cross ligament damage, posterior cruciate ligament damage, intra-articular fracture, meniscus injury and septic knee, rheumatoid arthritis, patella, loose body of knee joint etc.In the situation that expectant treatment is invalid, operation becomes the solution gonalgia, handicapped important channel.
Since 20 century 70s, artificial joint is very rapid in the development of basic research, design production and clinical practice three aspects:, and knee surgery is extensively carried out.Estimate that the whole world approximately has more than 50 ten thousand people to accept the relevant knee surgeries such as artificial joint replacement because of wound, osteoarthritis, tumor etc. every year.In operation process, patient lies on the back on operating-table, and the suffering limb shape that becomes to go down on one's knees is placed perpendicular to operating-table, at knee joint position, offers operative incision.For the ease of in operation to the inspection in affected part with for operating theater instruments provides space, need to according to the operation technique of operating doctor require to change at any time suffering limb the amplitude of bending and stretching and in the angle position of turning up fixing.At present in operation process, patient's knee joint bend and stretch and in the angle adjustment of turning up by assistant, complete, by manpower, move and maintain suffering limb in specific position, and according to operation needs, adjust at any time.Under this surgical environments, medical personnel's working strength is large, and physical demands is high, and the stability of most important suffering limb is difficult to guarantee, and exist assistant to the not equal problem of the cooperate degree of understanding, technical merit and the operator of operation, the quality of operation is greatly affected.
At present, knee surgery assistive device both domestic and external has been fixed function mostly, and function ratio is more single, does simply and is summarized as follows:
The first kind: the just adjusting of patient foot position and fixing, as:
< < foot support > > for knee surgery, the patent No.: CN2668096Y;
In < < knee joint art, stretch and bend adjustable foot-operated localizer > >, the patent No.: CN102631273A;
< < Split adjustable knee joint fixer > >, the patent No.: CN201879833U;
< < SURGICAL KNEE HOLDER > >, the patent No.: US4136858.
But with regard to operative process, although these inventions have realized the position change in certain stroke and definite in sick bed direction, also there are the following problems:
1) regulate part stepping position, can not realize the fixing of the interior optional position of stroke, operation bad adaptability;
2) while changing foot position, need to lift patient foot, make complicated operation, inconvenience, the risk of increase operation process secondary damage, safety is low;
3) can not realize any change of foot's attitude and fix, as patient's shank swinging at operating-table width.
Equations of The Second Kind: the just adjusting of patient's lower leg portion position and fixing, as:
< < support for fixing cnemis intramedullary pin > >, the patent No.: CN2880001Y;
But with regard to operative process, although these inventions have realized position change and definite in patient's shank certain limit, also there are the following problems:
1) regulate part stepping position, can not realize the fixing of the interior optional position of certain limit, operation bad adaptability;
2) in adjustment operation process, need medical personnel to lift patient's shank, loaded down with trivial details effort, the risk of increase operation process secondary damage, safety is low;
3), due in operation process, the location positioning of patient's buttocks, foot and governor motion, has limited the range of accommodation of shank, and such design can not meet the long patients' of different lower limbs demand.
The 3rd class: realized the adjusting of patient's knee joint part position and fixing, the position adjustments that has also indirectly realized patient's shank and leg portion simultaneously with fixing as:
< < lower limb operation bracket > >, the patent No.: CN202078397U;
< < knee-joint support frame > >, the patent No.: CN202173556U;
< < knee joint cavity puncture special stand > >, the patent No.: CN202437599U;
Knuckle support > > on < < operating-table, the patent No.: CN202497396U;
Mono-kind of < < is for knee sprung position operation support for lower limbs > >, the patent No.: CN202637125U;
But with regard to operative process, although these inventions have realized position change and definite in patient's knee joint certain limit, but all can only realize the change of simple knee joint and operating-table spacing or the change of the angle between shank and thigh, can not realize the patient foot, shank and the thigh that need in operation optional position and attitude fixing in operation technique claimed range.
For another example the < < knee arthroscope operation stent > > (patent No.: CN102499843A) that the First Affiliated Hospital of Third Military Medical University of PLA is invented, combine and regulate and fixation, but range of accommodation is limited, operation adjustment process is loaded down with trivial details, complex structure, can not meet the long patient's of different lower limbs demand, the impression while there is no doctor and corrective surgery in the consideration operation process of hommization.For another example the < < Universal support for arthroscopic knee surgeries > > (patent No.: CN201437000U) that Apex (Guangzhou) Tool & Orthopedics company holds, at shank, fix in this function more perfect, but complex structure, complicated operation, be not easy to dismantle the cleaning that carries out disinfection, cannot meet the functional requirement of modern operation.
At present, comparatively perfect knee joint fixator has:
1. the knee joint fixator (patent No. US5462551) of the people such as U.S. James R.Bailey application, well having realized patient foot movement, rotation and position within the specific limits fixes, but in actual operation process, patient's shank needs fixed pose sometimes, sometimes need low-angle torsion and swing, this design can not realize the fixing of shank attitude.
2. (this design patent is separately application to the DeMayo Knee Positioner of U.S. Edward N.DeMayo application, partial monopoly number: US8048082B1, US7003827B2) realize patient foot movement, rotation and position within the specific limits and fixed, also completed fixing patient's shank simultaneously.But still exist a lot of not enough:
1) in this design, move the position of patient foot is to be completed by slide block and guide rail, and fixedly time, and slide block and guide rail, slide block and foot fixedly boots synchronize sealed, the traditional Chinese medical science that is unfavorable for performing the operation is given birth to the lower limb of controlling flexibly patient, and patient's shank swings such as the invariant position of control pin.
2) support of this design adjusting part is mainly that a manual adjustment (adjusting) lever and pressure release fine setting lever form, and can only realize one-level and regulate, and can not realize adjusting among a small circle at any time in operation process.
3) operating process of the support of this design adjusting part is first to cross location then pressure release.First control manual adjustment (adjusting) lever patient's thigh is held out against, after fixing, by pressure release fine setting lever, carry out pressure release again.This design may make to pull in patient's ligament is holding out against process, meanwhile, range of accommodation poor controllability, the small range regulation of pressure release fine setting lever can not meet the distance adjustment demand producing due to operations such as cutting ligamena collateralia in operation process.
4) when needs patient thigh position change, the position of whole device and thigh contact portion can not change thereupon, thereby causes, when the patient in the face of different lower limbs length, there will be and because contact area is too little, causing fixing shakiness, or pressure is too large, can not keep the unobstructed of patient's lower limb blood.
